Examples of com.peterhi.runtime.Buffer.readable()

com.peterhi.runtime.Buffer.readable()
Gets the number of {@code bit}s that are currently available for reading. Reading data beyond this number will, depending on the methods you call, end up either returning an {@link #EOF}, or throwing a {@link InsufficientBufferException} ora {@link EOFException}. @return The number of {@code bit}s that are currently available for reading.

      byte[] existingData = new byte[] { -1, -1 };
      Buffer existingDataOffsetLengthBitsNotAligned = new Buffer(existingData, 4, 10, false);
      assertEquals(2, existingDataOffsetLengthBitsNotAligned.size());
      assertEquals(14, existingDataOffsetLengthBitsNotAligned.readable());
      assertEquals(14, existingDataOffsetLengthBitsNotAligned.written());
